I am trying to implement matrix multiplication with multiple threads. Everything seems to work correctly, however, it work much slower than the usual algorithm. Here is my code Here, I create a new thread for each element in the resulting matrix. I than write these threads to an array, start them and, finally, wait for them to finish working. I’ve

Matrix multiplication in Java using 2D ArrayLists
I am trying to implement a simple matrix multiplication in Java, where I am storing the matrices in two-dimensional ArrayLists. It would seem the error is caused by the setting of matrix Result, inside the nested for loop, but I do not understand why. The code produces the result: when in fact it should be: Answer The Result is incorrectly
How to fix a matrix multiplication in Java
I’m creating a class in Java to perform simple operations with matrices using two-dimensional arrays. I’m running into a problem with my method for matrix multiplication. Whenever I test my multiply method, no error appears, but my computer CPU utilization increases quite a bit and my tester program never finishes. This is my multiply method: Where I construct a matrix
Multiplying two matrices in Java
I am currently developing a class to represent matrices, it represents any general mxn matrix. I have worked out addition and scalar multiplication but I am struggling to develop the multiplication of two matrices. The data of the matrix is held in a 2D array of doubles. The method looks a little bit like this: It will return the product
